Since getting my replacement Rezound & updating to ICS I've had an intermittent problem & was wondering if anyone else has experienced it. At random times various shortcuts on the screen won't work. For example I have the Facebook app on my main screen...when I press on it to open it nothing happens. It's like it's not even registering that I'm pressing on it but other shortcuts on the main screen work fine. And if I open up all apps I can press on & open Facebook just fine. Has happened at random times with different shortcuts.
